Suffering is not always an evil. It is often educative. All evil is then seen to spring from separativeness, which is a stage inevitable to all creatures as they follow the line of unfoldment. Evil therefore is the adverse element in Nature. Man can conquer it in his mind by conquering separativeness and realizing the All as himself. At the same time he discovers that the whole creation is really a mental one, hence like but not the same as a dream; and if he keeps awake to the Static Reality whilst in the midst of the earthly dream, the whole world becomes merely a school for educating consciousness. Then suffering, evil, and the like are transient aspects leaving permanent results.
